The plurality of control apparatuses 200 and 300 may be classified as the control apparatus 200 and the control apparatus 300 (also referred to as ‘the second control apparatus 300’), according to whether a display unit is included.

The control apparatus 200 indicates a control apparatus that includes a display unit 210. According to an exemplary embodiment, the control apparatus 200 may be embodied as an independent apparatus designed to control the display apparatus 100. According to an exemplary embodiment, the control apparatus 200 may be embodied as one of various electronic apparatuses including smart devices such as a smartphone, a tablet computer, etc., a portable electronic apparatus, a wearable device, a home terminal that is connectable to a home network, or the like.

The second control apparatus 300 may be a control apparatus that does not include a display unit. Examples of the second control apparatus 300 include, but are not limited to, a TV remote controller, a pointer, a mouse, a motion recognizer, or the like.

FIG. 2 is a flowchart of an operating method of the display system 1000 of FIG. 1, according to at least one exemplary embodiment.

Referring to FIGS. 1 and 2, the display apparatus 100 may obtain a status signal. The status signal may indicate, for example, whether the control apparatus 200 is activated, from the control apparatus 200 including the display unit 210 (S110). When the control apparatus 200 is activated, a user may control the display apparatus 100 by using the control apparatus 200.

The display apparatus 100 may select, based on the status signal, a mode from among a plurality of modes that are categorized according to whether a UI display is limited or not, and may operate in the selected mode (S120). The plurality of modes may include a UI display limit mode that limits a UI display and a UI display mode that does not limit the UI display. The UI display limit mode is an operation mode during which the display apparatus 100 does not output a UI provided for manipulation of the display apparatus 100, or limits an output of the UI.

During the UI display limit mode, the display apparatus 100 may output only image content. Alternatively, during the UI display limit mode, the display apparatus 100 may output image content and only a part of a UI related to the image content. The UI display mode is an operation mode during which the display apparatus 100 does not limit an output of a UI.

When the obtained status signal indicates, for example, that the control apparatus 200 is inactivated, the display apparatus 100 may operate in the UI display mode.

When the obtained status signal indicates, for example, that the control apparatus 200 is activated, the display apparatus 100 may operate in the UI display limit mode. While the display apparatus 100 operates in the UI display limit mode, the display unit 210 of the control apparatus 200 may output a UI for manipulation of the display apparatus 100. The UI displayed on the display unit 210 of the control apparatus 200 may be displayed based on information received from the display apparatus 100, or may be displayed based on image information pre-stored in the control apparatus 200. Therefore, while the user manipulates the display apparatus 100 by using the UI that is output to the control apparatus 200, the display apparatus 100 may output only image content, or may output the image content and only some graphical objects related to the image content. For example, some graphical objects related to the image content may include a subtitle that corresponds to the image content, information that describes the image content, or the like.

Accordingly, the user may watch the image content that is not obstructed by the UI, and thus, a level of satisfaction of the user may be increased.

FIG. 3 is a flowchart of an operating method S200 of the display apparatus 100 of FIG. 1, according to at least one exemplary embodiment. Referring to FIGS. 1 and 3, the display apparatus 100 may obtain a status signal indicating, for example, whether the control apparatus 200 including the display unit 210 is activated (S210). The display apparatus 100 may determine, based on the status signal, whether the control apparatus 200 is activated (S220).

The control apparatus 200 may be activated or inactivated according to a user input. The control apparatus 200 may receive, from the user, an input for selecting whether to activate the control apparatus 200.

According to an exemplary embodiment, the control apparatus 200 may be activated or inactivated by turning on or off power of the control apparatus 200. For example, similar to an infrared (IR) remote controller that is activated by turning on power of the IR remote controller and is inactivated by turning off the power of the IR remote controller, the control apparatus 200 may be activated or inactivated by turning on or off the power of the control apparatus 200.

According to an exemplary embodiment, the control apparatus 200 may be activated or inactivated by turning on or off the display unit 210 of the control apparatus 200. For example, in a case of a general smartphone, when the smartphone is used while power of the smartphone is turned on, power of a display unit may be turned on, and when the smartphone is not used, the power of the display unit may be turned off and the smartphone may enter a standby mode. When a user wants to use the smartphone, the user may turn on the power of the display unit of the smartphone and thus may use the smartphone. The control apparatus 200 may be embodied in a similar manner to the activated or inactivated status of the smartphone, and thus, the control apparatus 200 may be activated by turning on power of the display unit 210 while the power of the control apparatus 200 is turned on. When the control apparatus 200 enters a standby mode or the power of the display unit 210 of the control apparatus 200 is turned off, the control apparatus 200 may be inactivated. The status signal may correspond to information about an on or off status of the display unit 210.

When the power of the control apparatus 200 or the display unit 210 is turned on, the control apparatus 200 may be activated. On the other hand, when the power of the control apparatus 200 or the display unit 210 is turned off, the control apparatus 200 may be inactivated. Whether to turn the power of the control apparatus 200 or the display unit 210 on or off may be determined, for example, based on an input from the user. The control apparatus 200 may receive, from the user, an input for commanding to turn on or off the power of the display unit 210. Alternatively, if the control apparatus 200 does not receive any input from the user for a preset time period, the power of the display unit 210 may be turned off.

According to an exemplary embodiment, when the control apparatus 200 is a generally-used electronic apparatus such as a smartphone or a tablet PC, activation or inactivation of a control function to control the control apparatus 200 may be realized by using a signal that is different from a signal for turning on or off a power or a display unit of the smartphone or the tablet PC. For example, if the control apparatus 200 is a generally-used electronic apparatus, an application may be separately arranged to indicate activation or inactivation of a display apparatus control function. For example, an application item for activation or inactivation of a display apparatus control function may be included in a menu of the control apparatus 200 that is embodied as a smartphone, and a user may activate the display apparatus control function by selecting the application item or may inactivate the display apparatus control function by deselecting the application item.

According to an embodiment, when activation of the control apparatus 200 is determined, the control apparatus 200 may obtain the status signal indicating whether the control apparatus 200 is activated, and may transmit the status signal to the display apparatus 100. The status signal may include mode selection information indicating in which mode the display apparatus 100 is to operate from among the plurality of modes. The display apparatus 100 may obtain the status signal by receiving the status signal. The status signal may be transmitted or received via short-distance communication.

The status signal may be a physical signal such as light, sound, or a motion. The display apparatus 100 may obtain the status signal by sensing the status signal output from the control apparatus 200. The display apparatus 100 may include a sensor capable of sensing the status signal. The control apparatus 200 may monitor whether the status signal is sensed, for example, according to predefined rules.

For example, the status signal may indicate a presence or absence of light due to the on or off status of the display unit 210. The display apparatus 100 may sense the light emitted from the turned-on display unit 210, and thus may obtain the sensed light as the status signal. When the display apparatus 100 senses the light, the display apparatus 100 may determine that the display unit 210 is turned on and the control apparatus 200 is activated. When the display apparatus 100 does not sense the light emitted from the display unit 210 of the control apparatus 200, the display apparatus 100 may determine that the display unit 210 is turned off and the control apparatus 200 is inactivated.

When the display apparatus 100 determines that the control apparatus 200 is activated, the display apparatus 100 may operate in the UI display limit mode (S230). When the display apparatus 100 determines that the control apparatus 200 is inactivated, the display apparatus 100 may operate in the UI display mode (S240).

FIG. 4 is a flowchart of an operating method of the display system 1000 of FIG. 1, according to at least one exemplary embodiment.

Referring to FIGS. 1 and 4, the display apparatus 100 may obtain a status signal indicating, for example, activation of the control apparatus 200 including the display unit 210 (S310). The display apparatus 100 may operate in the UI display limit mode (S320).

The display apparatus 100 may transmit a feedback signal to the control apparatus 200 (S330). The feedback signal may be a signal to notify the control apparatus 200 that the display apparatus 100 operates in the UI display limit mode. The transmission of the feedback signal may be skipped.

The display unit 210 of the control apparatus 200 may display a UI for manipulation of the display apparatus 100 (S340). The control apparatus 200 may determine a UI to be displayed on the display unit 210, based on the feedback signal, and may output the determined UI. The output UI may be received in real-time from the display apparatus 100. The UI may be output based on the image information pre-stored in the control apparatus 200.

The control apparatus 200 may receive, from a user, an input of a control signal to control an output from the display apparatus 100 (S350). The control signal may turn on or off the power of the display apparatus 100, may change a channel of the display apparatus 100, may adjust a volume of the display apparatus 100, may change a type of broadcasting from among terrestrial broadcasts, cable broadcasts, satellite broadcasts, or the like, or may be a command for setting a configuration, but examples of the control signal are not limited thereto.

The control apparatus 200 may transmit the control signal to the display apparatus 100 (S360). The display apparatus 100 may control the output from the display apparatus 100, based on the control signal (S370).

FIG. 5 is a flowchart of an operating method of the display system 1000 of FIG. 1, according to at least one exemplary embodiment.

Referring to FIGS. 1 and 5, the display apparatus 100 may obtain a status signal indicating, for example, activation of the control apparatus 200 including the display unit 210 (S410). The display apparatus 100 may operate in the UI display limit mode (S420). The display apparatus 100 may transmit a feedback signal to the control apparatus 200 (S430). The display unit 210 of the control apparatus 200 may display a UI for manipulation of the display apparatus 100 (S440). The control apparatus 200 may receive, from a user, an input of a control signal to control an output from the display apparatus 100 (S450). The control apparatus 200 may transmit the control signal to the display apparatus 100 (S460). The display apparatus 100 may control the output from the display apparatus 100, based on the control signal (S470). Descriptions with respect to operations S310 through S370 of FIG. 4 may be applied to operations S410 through S470.

The second control apparatus 300 that does not include a display unit may transmit a second control signal to the display apparatus 100 (S480). The second control signal may be a signal that commands that the display apparatus 100 be controlled.

If the second control signal is transmitted from the second control apparatus 300 to the display apparatus 100 while the display apparatus 100 operates in the UI display limit mode, the display apparatus 100 may block the second control signal (S490). That is, the display apparatus 100 may ignore the second control signal and thus may prevent the display apparatus 100 from being controlled according to the second control signal.

The display apparatus 100 may determine whether to block the second control signal, for example, according to types of the second control signal. The types of the second control signal may depend on whether it is required for the display apparatus 100 to output a UI or not. If the second control signal is a signal for commanding the display apparatus 100 to output a UI, the display apparatus 100 may block the second control signal. For example, the second control signal for commanding the display apparatus 100 to output the UI may be a signal for commanding that a search window for searching for image content be output, or may be signal for commanding that a list window showing a list of a plurality of pieces of image content be output.

If the second control signal is a signal to control the display apparatus 100 without outputting a UI to the display apparatus 100, the display apparatus 100 may not block the second control signal, and may control the display apparatus 100 according to the second control signal. For example, the second control signal to control the display apparatus 100 without outputting a UI to the display apparatus 100 may be a signal for turning on or off the power of the display apparatus 100, a signal for changing a channel of the display apparatus 100, a signal for adjusting a volume of the display apparatus 100, or the like.

FIG. 6 is a flowchart of an operating method of the display system 1000 of FIG. 1, according to at least one exemplary embodiment.

Referring to FIGS. 1 and 6, the display apparatus 100 may obtain a status signal indicating, for example, inactivation of the control apparatus 200 including the display unit 210 (S510). The display apparatus 100 may operate in the UI display mode (S520).

The second control apparatus 300 that does not include a display unit may transmit a third control signal to control the display apparatus 100 to the display apparatus 100 (S530). The third control signal may be a signal that commands the display apparatus 100 to output a UI. The third control signal may include information indicating a type of the UI to be output to the display apparatus 100. The display apparatus 100 may display the UI, based on the third control signal (S540).

The second control apparatus 300 may transmit a fourth control signal to the display apparatus 100 (S550). The fourth control signal may be a signal for commanding execution of a function related to the UI that is output to the display apparatus 100 according to the third control signal. For example, if the output UI is a search window, the fourth control signal may include a text to be input to the search window. if the output UI is a list window showing a list of a plurality of pieces of image content, the fourth control signal may be a signal for selecting one piece of image content from the list window. However, a type of the fourth control signal is not limited thereto, and the fourth control signal may be one of various types of a signal to control the display apparatus 100.

The display apparatus 100 may control an output from the display apparatus 100, based on the fourth control signal (S560). The second control apparatus 300 may obtain each of the third control signal and the fourth control signal, based on inputs by the user.

As described with reference to FIGS. 5 and 6, the control apparatus 200 including the display unit 210 may have a priority of controlling the display apparatus 100, over the second control apparatus 300. That is, as described with reference to FIG. 5, in a case where the control apparatus 200 including the display unit 210 is activated and thus the display apparatus 100 operates in the UI display limit mode, the second control apparatus 300 cannot control the display apparatus 100. According to an embodiment, in this case, only the control apparatus 200 can control the display apparatus 100. As described with reference to FIG. 6, in a case where the control apparatus 200 is inactivated and thus the display apparatus 100 operates in the UI display mode, the second control apparatus 300, for example, can control the display apparatus 100.

FIG. 7 illustrates an example in which the display apparatus 100 that operates in the UI display mode changes its mode to the UI display limit mode.

Referring to FIG. 7, the display apparatus 100 that operates in the UI display mode may output, for example, not only image content 11 but also may output UIs 12, 13, and 14. For example, while the display apparatus 100 outputs only the image content 11, the display apparatus 100 may receive the third control signal from the second control apparatus 300 (as illustrated in FIG. 1) as described, for example, with reference to S530 of FIG. 6. The display apparatus 100 may display the UIs 12, 13, and 14, based on the third control signal (refer to S540 of FIG. 6).

For example, the UIs 12, 13, and 14 may be used in selecting image content to be output by the display apparatus 100. As examples of the UIs 12, 13, and 14, FIG. 7 illustrates the UI 12 for providing a web browsing window for browsing image content on the Internet, the UI 13 to receive an input for selecting a TV broadcasting program, and the UI 14 to receive an input for selecting image content delivered from an external apparatus other than a TV signal, or selecting image content stored in the display apparatus 100. FIG. 7 illustrates examples of the UIs 12, 13, and 14, but types of the UIs 12, 13, and 14 are not limited thereto. The display apparatus 100 may display UIs that are variously implemented to control the display apparatus 100. The display apparatus 100 may support multiple screens as illustrated in FIG. 7.

The display apparatus 100 that operates in the UI display mode may change a UI displayed on the display apparatus 100, based on a user input via the second control apparatus 300 (refer to FIG. 1), or may change a screen of the display apparatus 100 so as to output image content selected according to a user input. The display apparatus 100 may be changed from the UI display mode to the UI display limit mode.

The display apparatus 100 that operates in the UI display mode and thus outputs the image content 11 and the UIs 12, 13, and 14 may receive a status signal indicating that the control apparatus 200 has been activated. The display apparatus 100 may change its mode to the UI display limit mode and thus may change its screen so as to output only the image content

The display unit 210 of the activated control apparatus 200 may display UIs 21, 22, and 23 for manipulation of the display apparatus 100. As examples of the UIs 21, 22, and 23, FIG. 7 illustrates the UI 21 for providing a web browsing window for browsing image content on the Internet, the UI 22 to receive an input of selecting a TV broadcasting program, and the UI 23 to receive an input for selecting image content delivered from an external apparatus other than a TV signal, or selecting image content stored in the control apparatus 200 or the display apparatus 100.
